Description
Technical Field
The present application relates to the field of communications, and in particular, to a Reference Signal (RS) transmission method, a user equipment and a network device.
Background
In the prior art, a network device sends a control signaling to a User Equipment (User Equipment, abbreviated as UE), and notifies uplink and/or downlink resources allocated to the UE by the network device to the UE, or notifies configuration information to the UE, so that the UE performs corresponding sending or receiving.
In the prior art, different types of RSs are designed for different purposes, for example, in a Long Term Evolution (LTE) system, an uplink RS includes a demodulation Reference Signal (DM RS) for demodulation and a Sounding Reference Signal (SRS) for measuring a wireless Channel, and a downlink RS includes a DM RS for demodulation and a Channel State Information-Reference Signal (CSI-RS) for measuring a wireless Channel.
In the above behavior example, the network device sends a Radio Resource Control (RRC) signaling to the UE to notify the UE of the SRS configuration (that is, after the network device sends the SRS configuration to the UE, the network device always uses the SRS configuration until the next time a new SRS configuration is sent), and dynamically triggers the UE to send the SRS, for example, an aperiodic SRS in the LTE system, through a dynamic scheduling signaling; for DM RS, the DM RS is transmitted along with a Physical Uplink Shared CHannel (PUSCH), and occupies the same frequency resource as the PUSCH, and the PUSCH is scheduled by a dynamic scheduling signaling sent by a network device to a UE, that is, the network device generally schedules the PUSCH once by sending the dynamic scheduling signaling once, and notifies the UE of the configuration of the DM RS in the dynamic scheduling signaling at the same time.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. The following embodiments or features of the embodiments can be combined with one another without contradiction.
In this application, the network device may be a Base Station (BS), an Access Point (AP), a Remote Radio Equipment (RRE), a Remote Radio Head (RRH), a Remote Radio Unit (RRU), or a Relay node (Relay node). The relationship between the network device and the cell is not limited, and one network device may correspond to one or more cells, or one cell may correspond to one or more network devices. The user equipment may be a Mobile Terminal (MT), a mobile user equipment, etc., which may communicate with one or more core networks via a Radio Access Network (RAN, for example), and may be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device.
The RS in the present application may be used for detecting a wireless environment (including wireless channel fading, Interference condition, or Signal to Interference plus Noise Ratio (SINR) and the like) or a Signal for demodulation, and is not used for transmitting any data information. Transmission in this application includes sending or receiving, e.g., transmission RS includes sending or receiving RS.
The present embodiment provides a method for transmitting a reference signal RS, which can reduce signaling overhead for notifying a UE of RS configuration, thereby improving system efficiency.
The present embodiment provides a method for transmitting an RS, which may be implemented by a UE or a relay. Fig. 1 is a flowchart of a method for transmitting an RS according to an embodiment of the present invention, as shown in fig. 1, the method including:
step 101, receiving a control signaling from a network device, wherein the control signaling includes orthogonal resource information;
step 102, determining orthogonal resources corresponding to each RS of at least two types of RSs according to the orthogonal resource information;
and 103, transmitting the RS corresponding to the determined orthogonal resource by using the orthogonal resource determined in the step 102.
In this embodiment, a control signaling of a network device is received, orthogonal resources of multiple types of RSs are determined according to orthogonal resource information in the control signaling, and the determined orthogonal resources are used to transmit RSs of corresponding types. Therefore, in the embodiment, the orthogonal resources of the RSs of different classes can be determined only according to one field of one signaling, thereby saving the overhead of notifying RS configuration and improving the system efficiency. In addition, since the control resources carry orthogonal resource information, that is, the resources determined according to the resource information sent to each UE and the resources determined according to the resource information sent to other UEs are orthogonal, orthogonal resources can be allocated to different UEs through fewer resources, and interference between RSs sent by each UE is reduced.
Preferably, under the condition that at least two types of RSs are a first type of RS and a second type of RS, a first orthogonal resource corresponding to the first type of RS and a second orthogonal resource corresponding to the second type of RS are determined according to the orthogonal resource information; then, the first type of RS may be transmitted using the first orthogonal resource and the second type of RS may be transmitted using the second orthogonal resource.
In this embodiment, at least two types of RSs are a first type of RS and a second type of RS, and according to this embodiment, when determining orthogonal resources for the two types of RSs, different signaling is not needed for determination, so that overhead in notifying RS configuration is saved, and system efficiency is improved.
Optionally, the orthogonal resource (e.g., the first orthogonal resource and/or the second orthogonal resource) includes at least one of: cyclic Shift (CS) resources, Orthogonal Cover Code (OCC) and comb fingers. Since the RS uses orthogonal resource information, the resource corresponding to each UE and the resources corresponding to other UEs are orthogonal, so that interference between RSs transmitted by the UEs can be reduced.
Preferably, determining the first orthogonal resource corresponding to the first type of RS and the second orthogonal resource corresponding to the second type of RS according to the orthogonal resource information includes: and determining the first orthogonal resource according to the first corresponding relation between the orthogonal resource information and the first orthogonal resource, and determining the second orthogonal resource according to the second corresponding relation between the orthogonal resource information and the second orthogonal resource. The first corresponding relationship and the second corresponding relationship may be a one-to-one corresponding relationship, a one-to-many corresponding relationship, a many-to-one corresponding relationship, or a many-to-many corresponding relationship, and the corresponding relationship may be embodied by a functional relationship, and may be implemented by presetting, for example, a preset corresponding relationship table, and by looking up a table.
As a preferred embodiment, if the control signaling is a control signaling for uplink scheduling, the orthogonal resource is a CS resource, and the orthogonal resource information includes CS number information n _ CS, determining that the first orthogonal resource may be, according to a first correspondence between the orthogonal resource information and information of the first orthogonal resource: determining that the CS number of the first orthogonal resource is:determining the first orthogonal resource according to the CS number of the first orthogonal resource; and/or, determining the second orthogonal resource according to a second functional relationship between the orthogonal resource information and the information of the second orthogonal resource may be: determining that the CS number of the second orthogonal resource is: n _ CS mod N _2, and determining the second orthogonal resource according to the CS number of the second orthogonal resource. Where N _1 is the total number of resources of the first orthogonal resource, N _2 is the total number of resources of the second orthogonal resource, mod denotes a modulo operation,indicating a rounding down operation.
The following describes an implementation procedure of this embodiment by taking the first type RS as an SRS and the second type RS as a DM RS as an example. Other RSs can implement the present embodiment in a similar manner, which is not described herein. The network equipment sends the orthogonal code resource information n _ CS to the UE, and after receiving the orthogonal code resource information n _ CS, the UE determines the CS value of the SRS (first type RS) according to the n _ CSAnd CS value of DM RS (second type RS); the CS values of the SRS and the DM RS are different in value range, so that the CS values can be determined according to the CS valuesThe CS value of the SRS is determined according to N _ C Smod N-, where N _1 is the number of available resources of the SRS (8), and N _2 is the number of available resources of the DM RS (12), so that the network device may assign a CS value of 0 to the UE1 and a CS value of 6 to the UE2, the UE1 may determine that the CS values used by the UE1 for transmitting the SRS and the DM RS are both 0 according to the above formula, and the UE2 may determine that the CS values used by the UE2 for transmitting the SRS and the DM RS are 4 and 6 respectively according to the above formula.
The SRS may be located in a Time domain symbol numbered 13 in a Transmission Time Interval (TTI), the UE determines a length N2 of the SRS sequence, determines a base sequence with a length N2 from a group of base sequences corresponding to the cell, cyclically shifts the base sequence (hereinafter, simply referred to as cyclic shift, and the length after the cyclic shift is still N2), maps the sequence to a corresponding comb, performs Inverse Discrete Fourier Transform (IDFT) transform (the length is still N2), and finally generates the SRS with 1 symbol.
The DM RS may be located on time domain symbols numbered 3 and 10 in one TTI, the UE determines the length N1 of the DM RS sequence transmitted on each symbol, determines a base sequence with the length N1 from the base sequence group corresponding to the cell, performs cyclic shift (the length is still N1), and performs IDFT (the length is still N1). In particular, when the dynamic scheduling signaling may further include OCC information, the UE needs to load the OCC in the time domain for two DM RSs, for example, the OCC includes [ +1, +1] and [ +1, -1], and if the OCC allocated to the UE by the network device is [ +1, -1], the UE multiplies the first DM RS in the TTI by +1 and multiplies the second DM RS by-1, thereby finally generating a two-symbol DM RS.
Therefore, when the CS values corresponding to the SRS and the DM RS are calculated, the resources used for transmitting the SRS and the DM RS can be determined in the above manner. It should be noted that the SRS and DM RS generation methods described above are for illustration purposes and are not intended to limit the present application, and other SRS and DM RS generation methods may be used in the present embodiment as long as the methods require the use of orthogonal resource information.
Since both SRS and DM RS have one feature: the larger the cycle distance of the CS value is, the better the orthogonality is, so that by the design, the SRS and the DM RS are ensured to have good orthogonality. The cyclic distance corresponds to the mod operation, e.g., for SRS, the cyclic distance between CS values of 0 and 1 is the same as the cyclic distance between 0 and 7. Therefore, the present embodiment can reduce interference between various types of RSs.
The embodiment of the present invention further provides another RS transmission method, which may be implemented by a network device (e.g., a base station). Fig. 2 is a flowchart of another RS transmission method according to an embodiment of the present invention, and as shown in fig. 2, the method includes:
step 201, determining an orthogonal resource corresponding to each of at least two types of RSs;
step 202, sending a control signaling containing orthogonal resource information to the UE, where the orthogonal resource information is used to determine the orthogonal resource corresponding to each of the at least two types of RS;
step 203, transmitting the RS corresponding to the determined orthogonal resource with the UE using the determined orthogonal resource.
Preferably, the first type RS of the UE is transmitted using a first orthogonal resource determined according to the resource information, and the second type RS of the UE is transmitted using a second orthogonal resource determined according to the orthogonal resource information.
In this embodiment, a control signaling carrying orthogonal resource information is sent to the UE, a first type of RS is transmitted using a first orthogonal resource determined by the orthogonal resource information, and a second type of RS is transmitted using a second orthogonal resource determined by the orthogonal resource information. Therefore, in the embodiment, different signaling is not needed to determine the orthogonal resources of the RSs of different classes, thereby saving the overhead of notifying RS configuration and improving the system efficiency.
Preferably, an orthogonal resource corresponding to each of at least two types of RSs is determined for each of at least two UEs, and a control signaling is sent to the at least two UEs in the same TTI, wherein orthogonal resource information carried by the control signaling sent to each UE is different from orthogonal resource information carried by the control signaling sent to other UEs; and transmitting the RS corresponding to the orthogonal resource with the corresponding UE by using the determined orthogonal resource. For example, a first type of RS corresponding to the determined first orthogonal resource is transmitted with a corresponding UE using the determined first orthogonal resource, and a second type of RS corresponding to the determined second orthogonal resource is transmitted with a corresponding UE using the determined second orthogonal resource.
Optionally, if the at least two UEs are a first UE and a second UE, sending a control signaling carrying first orthogonal resource information to the first UE in the same TTI, and sending a control signaling carrying second orthogonal resource information to the second UE, where the first orthogonal resource information and the second orthogonal resource information are different; transmitting a first type RS of the first UE using a first orthogonal resource determined according to the first orthogonal resource information, transmitting a first type RS of the second UE using a first orthogonal resource determined according to the second orthogonal resource information, transmitting a second type RS of the first UE using a second orthogonal resource determined according to the first orthogonal resource information, transmitting a second type RS of the second UE using a second orthogonal resource determined according to the second orthogonal resource information, for example, a first type of RS from a first UE is received using a first orthogonal resource corresponding to first orthogonal resource information, a first type of RS from a second UE is received using a first orthogonal resource determined according to second orthogonal resource information, a second type of RS from the first UE is received using a second orthogonal resource determined according to the first orthogonal resource information, and a second type of RS from the second UE is received using a second orthogonal resource determined according to the second orthogonal resource information; or, the first orthogonal resource determined according to the first orthogonal resource information is used for sending the first type of RS to the first UE, the first orthogonal resource determined according to the second orthogonal resource information is used for sending the first type of RS to the second UE, the second orthogonal resource determined according to the first orthogonal resource information is used for sending the second type of RS to the first UE, and the second orthogonal resource determined according to the second orthogonal resource information is used for sending the second type of RS to the second UE.
In this embodiment, the orthogonal resource information sent to each UE is different, and therefore, the first orthogonal resource and the second orthogonal resource determined by each UE according to the orthogonal resource information are also different from those determined by other UEs, and when different UEs use different resources to generate mutually orthogonal RSs, interference between RSs sent by each UE is avoided or caused to approach 0.
Fig. 3 is a method for determining orthogonal resources of a reference signal RS according to an embodiment of the present invention. As shown in fig. 3, the method includes:
step 301, the network device sends a control signaling to the UE, where the control signaling includes orthogonal resource information. The Control signaling sent by the network device may be, for example, a Physical layer signaling (for example, a dynamic scheduling signaling, a Physical Downlink Control Channel (PDCCH for short) used for indicating uplink transmission in the LTE system), or may be a higher layer signaling (for example, an RRC signaling), and the implementation process of this embodiment is mainly described below with the PDCCH as an example.
Step 302, the UE acquires orthogonal resource information from the control signaling. Preferably, the orthogonal resource information is a field of control signaling.
Step 303, the UE determines orthogonal resources associated with each of at least two types of RSs according to the orthogonal resource information.
Step 304, the UE and the network device transmit the RS corresponding to the determined orthogonal resource using the determined orthogonal resource. For example, the UE transmits an RS corresponding to the determined orthogonal resource to the network device using the determined orthogonal resource, and the network device receives the RS corresponding to the determined orthogonal resource transmitted by the UE using the determined orthogonal resource; or, the network device transmits the RS corresponding to the determined orthogonal resource to the UE using the determined orthogonal resource, and the UE receives the RS corresponding to the determined orthogonal resource transmitted by the network device using the determined orthogonal resource.
In this embodiment, the network device can transmit the orthogonal resource information of at least two types of RSs to the UE only by sending the orthogonal resource information to the UE through one control signaling, thereby reducing overhead and improving system efficiency. In addition, since the control resources carry orthogonal resource information, that is, the resources determined according to the resource information sent to each UE and the resources determined according to the resource information sent to other UEs are orthogonal, orthogonal resources can be allocated to different UEs through fewer resources, and interference between RSs sent by each UE is reduced.
Preferably, under the condition that at least two types of RSs are a first type of RS and a second type of RS, a first orthogonal resource corresponding to the first type of RS and a second orthogonal resource corresponding to the second type of RS are determined according to the orthogonal resource information; and transmitting the first type of RS by using the first orthogonal resource, and transmitting the second type of RS by using the second orthogonal resource. In this embodiment, at least two types of RSs are a first type of RS and a second type of RS, and according to this embodiment, when determining orthogonal resources for the two types of RSs, different signaling is not needed for determination, so that overhead in notifying RS configuration is saved, and system efficiency is improved.
For example, in the uplink direction, the UE determines a first orthogonal resource for transmitting the first type RS and a second orthogonal resource for transmitting the second type RS according to the orthogonal resource information; and the UE sends the first type of RS to the network equipment by using the first orthogonal resource and sends the second type of RS to the network equipment by using the second orthogonal resource. The types of RSs used in the uplink direction include: SRS, DMRS and/or RS for sounding Interference or SINR use (i.e., Interference measurement reference Signal (IRS or IMRS for short)). In the prior art, the uplink RS only includes SRS and DM RS, and this embodiment also supports IRS. By using the embodiment, the signaling overhead required by the uplink RS can be reduced.
Optionally, in the downlink direction, the UE determines, according to the orthogonal resource information, a first orthogonal resource for receiving the first type of RS and a second orthogonal resource for receiving the second type of RS; and the UE receives the first type of RS sent by the network equipment by using the first orthogonal resource and receives the second type of RS sent by the network equipment by using the second orthogonal resource. The RS for the downlink direction includes at least one of: CSI-RS, DM RS, and IRS.
In this embodiment, the first RS and the second RS indicate two different types of RSs, regardless of the uplink direction or the downlink direction. The first RS and the second RS are different RSs with different purposes, for example, the first RS is an SRS and is used for sounding a radio channel; the second type of RS is DM RS, which is used for demodulating PUSCH. The orthogonal resource information for determining the orthogonal resources of the first-type RS and the second-type RS in this embodiment may be the same field.
Optionally, the orthogonal resource (e.g., the first orthogonal resource and/or the second orthogonal resource) includes at least one of: cyclic Shift (CS) resources, orthogonal mask OCC, and comb fingers. Since the RS uses orthogonal resource information, the resource corresponding to each UE and the resources corresponding to other UEs are orthogonal, so that interference between RSs transmitted by the UEs can be reduced.
In this embodiment, the RS using the CS resource may be generated by performing a mathematical transformation by cyclically shifting a base sequence of a certain length, where the length of the base sequence is the length of the RS, and thus in this embodiment, the cyclic shift is one of the orthogonal code resources (CS resources). In the LTE system, the process of generating the RS may include: the base station sends CS number information n _ CS to the UE, and the UE sends the CS number information n _ CS to the UE according to kCSThe final CS value k is obtained for (n _ CS + n (1) + n _ PN) mod 12CSThen pass throughPara base sequenceCyclic shift is performed and finally IDFT transform is performed on r (m) to generate RS. It is composed ofWhere M is the length of the base sequence, n (1) is the CS offset configured by the base station for all UEs of the cell, and n _ PN is the CS variation value over time.
Preferably, the UE may determine the first orthogonal resource corresponding to the first type RS and the second orthogonal resource corresponding to the second type RS by: and the UE determines the first orthogonal resource according to the first corresponding relation between the orthogonal resource information and the first orthogonal resource, and determines the second orthogonal resource according to the second corresponding relation between the orthogonal resource information and the second orthogonal resource. The correspondence (e.g., the first correspondence and/or the second correspondence) may be a functional relationship.
Optionally, the UE and the base station may also pre-store a corresponding relationship between the orthogonal resource information and the orthogonal resources corresponding to each RS, and the UE determines the orthogonal resources corresponding to each RS according to the orthogonal resource information and the corresponding relationship. For example, the UE and the base station pre-store a corresponding relationship between the orthogonal resource information and the first orthogonal resource and the second orthogonal resource, and the UE determines the first orthogonal resource and the second orthogonal resource according to the orthogonal resource information and the corresponding relationship.
Through the two preferred embodiments, the UE can determine the orthogonal resources of the RSs of different types only through one signaling, so that the orthogonal resources of the system are saved.
Preferably, the first correspondence relationship and the second correspondence relationship are different. And the method for determining the orthogonal resources of the first type of RS is different from the method for determining the orthogonal resources of the second type of RS according to the orthogonal resource information. For example, the function determining the first type of RS is different from the function determining the orthogonal resources of the second type of RS.
Due to the different uses of different types of RS, there are also differences in their design criteria. For example, in an LTE system, the minimum bandwidth granularity of an uplink SRS is 4 Physical Resource Blocks (PRBs), and the minimum bandwidth granularity of an uplink DM RS is 1 PRB, so that the orthogonal resources of the first type of RS and the second type of RS are respectively determined by different methods according to the same orthogonal Resource information, so that the determined orthogonal resources can be matched with the design of the first type of RS and the second type of RS, and the reasonable allocation of the orthogonal resources to a greater extent is ensured.
Optionally, if the control signaling is a control signaling for uplink scheduling, the orthogonal resource is a CS resource, and the orthogonal resource information includes CS number information n _ CS; the UE determines that the CS number of the first orthogonal resource is:determining a first orthogonal resource according to the CS number of the first orthogonal resource; and/or the UE determines that the CS number of the second orthogonal resource is: n _ CS mod N _2, the second orthogonal resource is determined according to the CS number of the second orthogonal resource, wherein N _1 is the total number of the resources of the first orthogonal resource, N _2 is the total number of the resources of the second orthogonal resource, mod represents the modulus operation,indicating a rounding down operation.
In the prior art, SRS and DM RS are generated in a similar manner, and are generated after performing IDFT, where the length of the base sequence is the length of SRS and DM RS, and the cyclic shift is an orthogonal code resource, and if a network device allocates the same frequency band and different CS values to different UEs, RSs transmitted by the two UEs are orthogonal, that is, there is no interference between them or the interference approaches to 0.
In an LTE system, network equipment sends CS information n _ CS _ SRS of the SRS to UE through RRC signaling, and the UE takes the n _ CS _ SRS as an orthogonal code resource of the SRS, wherein the value range of the n _ CS _ SRS is 0-7; for DM RS, the network equipment sends 3 bits to UE in a dynamic scheduling signaling to transfer a CS value n _ CS _ DMRS, and the UE determines orthogonal code resources of the DM RS according to the n _ CS _ DMRS, wherein the value range of the n _ CS _ DMRS is 0-11.
In this embodiment, the network device sends orthogonal code resource information n _ CS to the UE, and the UE receives the orthogonal code resource information n _ CS and then sends the orthogonal code resource information n _ CS to the UE according to n _ CSDetermining a CS value of the SRS and a CS value of the DM RS; the CS values of the SRS and the DM RS are different in value range, so that the CS values can be determined according to the CS valuesThe CS value of the SRS is determined, and the CS value of the DMRS is determined according to N _ CS mod N _2, where N _1 is the number of available resources of the SRS (8) and N _2 is the number of available resources of the DM RS (12), so that the network device may allocate a resource with a CS value of 0 to the UE1 and allocate a resource with a CS value of 6 to the UE2, the UE1 may determine that the CS values used by the UE1 for transmitting the SRS and the DM RS are both 0 according to the above formula, and the UE2 may determine that the CS values used by the UE2 for transmitting the SRS and the DM RS are 4 and 6 respectively according to the above formula. Since cyclic shifts of both SRS and DM RS have one feature: the larger the cyclic distance of the CS value, the better the orthogonality, and the cyclic distance corresponds to the mod operation, e.g., for SRS, the cyclic distance between CS values of 0 and 1 is the same as the cyclic distance between 0 and 7, and therefore, the SRS and DM RS resources determined by the above function can both be guaranteed to have good orthogonality.
Therefore, the embodiment can enable good orthogonality between the SRSs of different UEs and between the DM RSs of different UEs, and can ensure that interference between RSs sent by different UEs is the same for the two types of RSs, so that the network device can obtain channel information by measuring the SRS.
In addition, the embodiment in which the first-type RS and the second-type RS are SRS and DM RS is given above, and because the design of the IRS and the SRS is similar, for the embodiment in which the first-type RS and the second-type RS are IRS and DM RS, based on the same reason, with the present embodiment, it can also be ensured that interference between RSs sent by different UEs is the same for the two types of RSs, so that the network device can obtain interference or SINR by measuring the IRS.
The functional relationship may be simply modified, for example, the CS number of the first orthogonal resource may be added by 1 to the function, and the CS number of the second orthogonal resource may be similarly modified.
Alternatively, in the uplink direction, the first type RS may be a sounding reference signal SRS, and the second type RS may be a demodulation reference signal DM RS.
In this embodiment, the first type RS is an SRS, and the second type RS is a DM RS, which saves signaling overhead for notifying the UE of the SRS resource, i.e., the network device does not need to send RRC signaling to the UE to notify the SRS resource information.
The semi-static signaling includes broadcast signaling or RRC signaling, that is, after the network device sends the broadcast signaling or RRC signaling to the UE, the UE always uses the configuration of the broadcast signaling or RRC signaling until a new broadcast signaling or RRC signaling is sent next time. The invention can also send the orthogonal resource information to the UE through the semi-static signaling.
As another embodiment of the present invention, the following behavioral examples are explained here. In the LTE system, the network device sends a PDCCH to the UE, wherein OCC information is included to indicate the OCC allocated for the UE to receive DM RS. However, with the present invention, the UE determines a first orthogonal resource for the first RS type and a second orthogonal resource for the second RS type according to one orthogonal resource information sent by the network device, so as to receive the first RS type using the first orthogonal resource and receive the second RS type using the second orthogonal resource, for example, when the control signaling is control signaling for downlink scheduling, the orthogonal resource is an OCC, and the orthogonal resource information includes OCC number information n _ OCC, the UE determines that the number of the first orthogonal resource OCC is:the UE determines that the serial number of the second orthogonal resource OCC is: n _ OCC mod N _2, where N _1 is the total number of resources of the first orthogonal resource, N _2 is the total number of resources of the second orthogonal resource, mod denotes a modulo operation,indicating a rounding down operation.
By the embodiment, the RSs transmitted by different UEs can be orthogonal.
Preferably, the first type of RS is a channel state information reference signal, CSI-RS, and the second type of RS is a DM RS.
Optionally, the first type RS is an IRS and the second type RS is a DM RS.
In a preferred implementation manner of this embodiment, the first RS and the second RS use at least one of the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule, and CS hopping rule, for example, in the transmission process of the uplink RS, the IRS and the DM RS use the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule, or CS hopping rule, and in the transmission process of the downlink RS, the IRS and the DM RS use the same base sequence, base sequence group, sequence hopping rule, or sequence group hopping rule.
In the LTE system, generally, all UEs in one cell use the same motif group when transmitting RSs, and different cells use different motif groups, so that interference between RSs in cells is reduced because interference between different motif groups is small. In addition, the network device may also start the sequence hopping function or the sequence group hopping function by sending signaling to the UE, so that the DM RSs sent by the UE at different times use different base sequences or different base sequence groups, and the interference between the RSs in the cells can be further randomized (the RS sent by the UE may be interfered by RSs of different base sequences or base sequence groups at different times, so that the interference is not always strong or always weak, and the average interference level over time is ensured). The principle of CS hopping is similar to that of sequence group hopping, i.e., DM RSs transmitted by a UE at different times use different CSs, and the benefit of interference randomization can also be achieved.
By the embodiment, the IRS and the DM RS can use the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule or CS hopping rule, so that if the IRS is transmitted before the DM RS and the IRS and the DM RS occupy the same frequency band, the network device can estimate interference more accurately according to the result obtained by estimating interference by the IRS, which is similar to the interference actually received by the DM RS.
As another embodiment of the present invention, the first orthogonal resource is a comb, and the second orthogonal resource is an OCC; the UE determines comb teeth according to the first corresponding relation between the orthogonal resource information and the comb teeth; and determining the OCC according to the orthogonal resource information and the second corresponding relation of the OCC.
The second type of RS may be DM RS and the first type of RS may be SRS or IRS.
The following embodiments may be used for transmission of RS in the uplink direction and may also be used for transmission of RS in the downlink direction.
In the uplink transmission of the LTE, the network device may notify the UE of the OCC information, and after receiving the OCC information, the UE loads the OCC to the DM RS; however, since the SRS or IRS usually has only one RS symbol in the time domain, the OCC cannot be loaded in the time domain using the same method.
In this embodiment, the network device may send orthogonal resource information to the UE, and the UE may determine comb teeth of the SRS or the IRS according to the orthogonal resource information, and determine the OCC of the DM RS according to the orthogonal resource information. Thus, when the network device sends different orthogonal resource information to different UEs, the different UEs use different OCCs to guarantee orthogonality of DM RSs, and for SRS or IRS, use different comb fingers to guarantee orthogonality. For example, the network device sends 1 st orthogonal resource information to the UE1 and 2 nd orthogonal resource information to the UE2, wherein the first orthogonal information may indicate that the UE1 uses odd comb and OCC [ +1, +1], the first orthogonal information may indicate that the UE2 uses even comb and OCC [ +1, -1], and then the UE1 and the UE2 use OCC [ +1, +1] and OCC [ +1, -1], respectively, to generate DM RS and use odd comb and even comb, respectively, to generate SRS, thus ensuring that the two types of RS transmitted by different UEs are orthogonal.
The corresponding relation between different OCCs and comb teeth can be preset values at the UE and network equipment sides, or can be notified by the network equipment sending signaling to the UE, wherein the signaling can be broadcast signaling or RRC signaling. Therefore, only through OCC information, the UE can acquire OCC and comb teeth, and accordingly resources corresponding to different RSs are determined.
Optionally, the comb teeth comprise at least one of: odd number broach, even number broach, the sub-broach of odd number broach and the sub-broach of even number broach.
In one system, the SRS and IRS may be used differently and may both need to be transmitted by the UE. If the UE uses all comb fingers for transmitting SRS, there is no comb resources for transmitting IRS, and vice versa. Thus, the UE may be allocated a first comb for transmitting SRS and a second comb for transmitting IRS.
For the IRS, in order to keep the IRS transmitted by different UEs orthogonal when the network device allocates different orthogonal resources to different UEs, different OCCs of the DM RS may correspond to different sub-combs. For example, odd comb is used for transmitting IRS (i.e., UE transmits IRS using subcarriers numbered 1, 3, 5 … …), if the network device transmits 1 st, 2 nd orthogonal resource information to UE1 and UE2, UE1 and UE2 generate DMRS using OCC [ +1, +1] and OCC [ +1, -1] respectively, and transmit IRS using two sub-combs of the odd comb, i.e., transmit IRS using subcarriers numbered 1, 5, 9 … … and subcarriers numbered 3, 7, 11 … … respectively, which ensures: when the IRS occupies only one comb, the IRS transmitted by different UEs still remains orthogonal.
Preferably, the control signaling further includes a layer number indication for indicating the UE to transmit in n _ layer; the UE determines orthogonal resource information corresponding to each antenna port in the n _ layer antenna ports according to the orthogonal resource information and the serial number of each layer, determines a first orthogonal resource corresponding to a first RS transmitted by each antenna port according to the orthogonal resource information corresponding to each antenna port, and determines a second orthogonal resource corresponding to a second RS transmitted by each antenna port according to the orthogonal resource information corresponding to each antenna port; and transmitting the corresponding first-class RS through the corresponding n _ layer antenna ports by using the determined first orthogonal resource, and transmitting the corresponding second-class RS through the corresponding n _ layer antenna ports by using the determined second orthogonal resource.
The present embodiment may be applied to uplink or downlink MIMO scenarios. The following description will be given taking uplink MIMO as an example. In the prior art, the network device may send a control signaling to the UE to instruct the UE to send n _ layer data, so that the spatial characteristics may be utilized to improve efficiency. The present embodiment extends to a multi-layer transmission scenario, for example, if the network device instructs the UE to transmit layer 2 data, the UE determines the SRS and DM RS values of 2 antenna ports according to the orthogonal resource information, and transmits the SRS and DM RS values to the network device. The method for determining the CS value is not limited, for example, the orthogonal resource information includes CS number information N _ CS, and the UE may determine the CS value corresponding to the 2 antenna ports as N _ CSi according to N _ CS (for example, N _ CSi ═ N × N _2/N _ layer) mod N _2, where i ═ 0 and 1 represent the number of the layer, and further determine the CS values of the orthogonal resources of the first type RS corresponding to the two antenna ports as N _ CSi, respectivelyAnd determining that the CS values of the orthogonal resources of the second-class RSs corresponding to the two antenna ports are N _ CSi mod N _2 respectively. Downlink MIMO may use the same method, and is not described herein again.
Optionally, a first time period during which the UE transmits the first type RS and a second time period during which the UE transmits the second type RS belong to different transmission time intervals, TTIs.
The first time interval and the second time interval are usually preset at the UE and the network device side, for example, when the network device sends the control signaling to the UE in the TTI numbered n, the UE sends the first type RS in the TTI numbered n + n1, and sends the second type RS in the TTI numbered n + n2, where n1 and n2 are fixed values.
For example, the first time period is the last symbol of the TTI numbered n +1, and the second time period is two symbols numbered 3 and 10 of the TTI numbered n +4, so that the UE can process the RS of the first type first after the first time period arrives by using the interval between the first time period and the second time period, and process the RS of the second type after the second time period arrives, which can be implemented by the UE conveniently; in addition, if the first type RS can help to adjust the scheduling of the PUSCH (the PUSCH and the DM RS are transmitted in the same TTI), the first time period and the second time period belong to different TTIs, that is, the first type RS and the second type RS are respectively transmitted in different TTIs, which is beneficial for the network device to adjust the scheduling of the PUSCH according to the measurement result of the first type RS after receiving the first type RS, so that the scheduling of the PUSCH is more matched with the change of the channel environment. The downlink transmission is similar and will not be described herein.
Preferably, the orthogonal resource information includes at least one of: code orthogonal resource information and comb resource information.
Generally, for convenience, the relationship between the time when the network device transmits the control signaling and the time when the UE transmits the RS is fixed, for example, in the LTE system, the network device transmits the control signaling in the TTI numbered n, and the UE transmits the DM RS in the TTI numbered n +4, so the orthogonal resource information in this embodiment does not include the time resource information, which has the advantage of easy implementation.
Assuming that the first RS is an SRS and the second RS is a DM RS, the network device sends the control signaling to the UE in the TTI numbered n, the UE may send a PUSCH including the DM RS in the TTI numbered n +4, and send the SRS in the first TTI larger than n +6, where the control signaling may include: code orthogonal resources, and the UE transmits SRS and DM RS by using corresponding code resources according to the control signaling; the code comprises an orthogonal code; in the uplink direction of the LTE system, as mentioned above, the code resource may be a CS resource, and when different UEs transmit DM RS or SRS corresponding to different CS resources on the same frequency band, signals transmitted by the UEs may be orthogonal to each other.
Optionally, the network device sends control signaling to the at least two UEs in the same TTI, where orthogonal resource information carried by the control signaling sent to each of the at least two UEs is different from orthogonal resource information carried by control signaling sent to other UEs in the at least two UEs; the network equipment transmits a first type of RS corresponding to the determined first orthogonal resource by using a first orthogonal resource determined according to the orthogonal resource information sent to each UE, and transmits a second type of RS corresponding to the determined second orthogonal resource by using a second orthogonal resource determined according to the orthogonal resource information sent to each UE.
For example, if at least two UEs are a first UE and a second UE, the network device sends a control signaling carrying first orthogonal resource information to the first UE in the same TTI, and sends a control signaling carrying second orthogonal resource information to the second UE, where the first orthogonal resource information and the second orthogonal resource information are different; the network equipment receives a first type of RS from a first UE by using a first orthogonal resource determined according to the first orthogonal resource information, receives a first type of RS from a second UE by using a first orthogonal resource determined according to the second orthogonal resource information, receives a second type of RS from the first UE by using a second orthogonal resource determined according to the first orthogonal resource information, and receives a second type of RS from the second UE by using a second orthogonal resource determined according to the second orthogonal resource information; or, the network device sends the first type of RS to the first UE using the first orthogonal resource determined according to the first orthogonal resource information, sends the first type of RS to the second UE using the first orthogonal resource determined according to the second orthogonal resource information, sends the second type of RS to the first UE using the second orthogonal resource determined according to the first orthogonal resource information, and sends the second type of RS to the second UE using the second orthogonal resource determined according to the second orthogonal resource information.
